Telecommunications On August 30, Samsung Electronics has showed off its vision for the future of mobile technology, sending data wirelessly at blazing speeds to a moving minibus. The connection was robust enough to support live images.including a high-definition movie.beamed from a conference Samsung is hosting here on fourth-generation, or 4G, wireless. In a key step toward making the technology truly mobile, the device aboard the minibus switched seamlessly between two base stations meaning the signal won't be lost when users are onthe- go. The current prototype allows data transfers of 100 megabits per second, about 30 times typical broadband Internet speeds. It works even when the receiver is moving as fast as 75 mph. But the promise is still far off. Currently, Samsung's data receiver is the size of a compact refrigerator. It won't be until 2008 that the device can be shrunk to fit in a mobile phone, said Lee Ki-tae, president in charge of the information and telecommunications division. And even then, frequencies need to be allocated and standards set, meaning the devices aren't expected to be in consumers' hands until after 2010. The promises of yet another new wireless technology are familiar. Mobile phone companies are still feeling the burn from their much-hyped third-generation technology. It costs billions in license fees and is now being implemented worldwide, but so far has yet to make much profit. Now again, engineers boast of providing the world with even higher-speed wireless connections that make information accessible anywhere at anytime, enabling phone calls, quick movie and music downloads, and fast Web-surfing. Wireless companies realize consumers need a truly compelling reason to embrace the gadgets that seek to blend different functions.
